Bio-Plex Assay Builder

Use the Bio-Plex® Assay Builder to design your customized Bio-Plex Assay in four easy steps

The Bio-Plex Pro RBM kidney toxicity assays, developed in partnership with Myriad RBM, comprise a highly relevant set of biomarkers for early detection and characterization of kidney toxicity/injury. Myriad RBM’s close collaboration with the Predictive Safety Testing Consortium (PSTC), FDA, and European Medicines Evaluation Agency (EMEA) was instrumental in the selection of markers found in these panels.

The assays are built on magnetic beads to enable robust quantification of multiple proteins in human urine samples, providing valuable information throughout drug development — from lead optimization to preclinical and clinical protocol decision making. Assays are offered as premixed all-in-one kits for research involving:

Drug-induced kidney toxicity

Diabetes

High blood pressure

Glomerulonephritis

Polycystic kidney disease

Chronic infection

SLE (lupus) and other autoimmune disorders

Bio-Plex Pro RBM human kidney toxicity assays are available as two panels:
